16 Claims.

This invention relates to a window guard which is attachable to windows of different .widths, which may be removably applied on the lower member of a window, when it is raised; and which may remain permanently in place when the window is closed, if desired. The invention further relates to a modification which is attachable to a window sash or frame, outside of the upper and not be removable.

Among the objects of the invention is to obtain a window guard which, when the upper and lower members of the window are closed, or partially so, is not removable, andwhich when the lower member is raised to its extreme upward position, is removable. A further object of the invention is to obtain a window guard whichis applicable to windows and window sashes of considerable variation in width, and which is equally efiective as a window guard whatever the width of the window may be to which it is applied. A further object is to obtain a window guard which is easily removed by a person not skilled in the art, whenever desired, and which, at the same time is not removable when it, and the lower member of the window which it guards, is in a determined position. A further object is to obtain a window guard which is effective to prevent entrance of any person or persons through the window opening when the guard is in place and the lower member of the window is open, and which cannot be removed by a person outside of the window. A further object is to obtain a window guard which is manufactured in a shop .35' or factory without special regard to the width of the window sash or frame to which it is to be applied, thereby rendering the cost of the same less than it would be if it were required to be made to precise measurements. A further object is toobtain a window guard which. is sightly in appearance, and which doesnot materially interfere with out-look therethrough.

I have illustrated the invention by the drawings accompanying and forming. a part hereof in which 1 is an elevation of a construction embodying the invention, viewed from within a room, attached to a window; with the lower end or sash or" the window raised and secured in a raised position. Fig. 2 is a horizontal section of one side of the window frame and sash illustrated in Fig. l, and one side of the construction embodying the invention illustrated in Fig. 1, taken on line 2-2 of said figure viewed in the direction indicated by arrows. Fig. 3 is a vertical section of like parts as in Fig. 2, taken on line 3.-3 of lower members of the window, and designed to Fig. 1, viewed'in'the direction indicated by arrows. Figs. 4 and 5 are perspectives of details forming elements of the construction illustrated in Figs. 1, 2 and 3.

Fig. 6 is a modification of the construction illustrated in Figs. 1 to 5, both inclusive, whereby said construction is applicable to the outside. of a Window frame or sash, by metermed irremovable or stationary.- Fig. .7 is a perspective of a member forming an element of the modification illustrated in Fig. 6; and Fig. 8 is a side or edge View of the member illustrated in Fig. 7 and of a connecting member which co-acts therewith.

Figs. 2, 3, 4, 5,. 7 and 8 are on an enlarged scale.

A reference character applied to designate a given part indicates said part throughout the several figures of the drawings, wherever the same appears.

1 represents bars, a plurality pivotally secured together by rivets2, form elements in the-construction of a window guard embodying the invention. 3 represents vertical bars or members. 4'represents additional vertical bars or members.

5 represents slots in vertical bars or members 3; and 6 represents slots in vertical bar or member 4. 7 represents an additional slot in vertical bar or member 4. 8 represents a bend adjacent to the upper end of vertical bar or member 4, (see 3), and 9 represents the upper ends of bars 35 or members 4, which end is in a substantially hori zontal plane. Vertical bars or members 3 are secured to adjacent ends of bars 1, by rivets 10. There are additional rivets 11 which extend through bars 1 and also through slots 5 and 6 in vertical bars or members 3 and 4, respectively. There are also bolts or rivets 12 which extend through bars land through slots '7, at the upper end of the vertical bar or member 4. The rivets 11, 12, respectively, are screw threaded, and provided with nuts 13, 14, (see Fig. 3). These nuts 13, 14, can be loosened to permit installation of the construction; but cannot be removed from the rivets 1-1, 12. The vertical bars or members 3 are provided with a'transverse aperture, 15, ad jacent to the lower end thereof, (see Fig. 3), 16, shown in detail in Fig. 4, represents a connecting member which is attached to the lower horizontal member X of a window frame, (Figs. 1, 2 and 3). Connecting member 16 is provided with the substantially right angle bend 17 to obtain the horizontal end or element 18, and the vertical end or element 19. The vertical end or element 19 is provided with bends 20, so that the upper end 21 thereof is in a Vertical plane parallel to the plane 119 in which part 19, adjacent to bend 1'7, is in. End 21 and the portion between bends 20, of the vertical end or element 19 is inserted in transverse aperture 15, adjacent to the lower ends of vertical bars or members 3, when the construction is installed in a window frame. The horizontal end or element 18 of connecting member 16, is provided with aperture 22, and 23 represents lips or projections which are forced up out of the body of said horizontal end or element 18. These lips or projections 23 are positioned to permit the head 24 of lag screw 25, to come between them, (Fig. 3). When the connecting member 16 is attached to horizontal member X of the window frame, upon the lag screw 25 being turned into member X a sufficient distance, the head of said lag screw coming between said lips or projections, requires the turning of connecting member 16 in unison therewith, as said lag screw is forced home. When the end 21 is inserted in aperture 15, in the lower end of vertical bar or member 3, said member 16 cannot be turned, and the lag screw 25 cannot thereafter be removed frommember X of the window frame,

26 represents a connecting member which is secured to the member X of the window frame. Connecting member 26 is provided with a substantially right angle bend, 2'7, (Fig. 5), to obtain the ends 28 and 32; which are in planes at right angles to each other. The end 23 is provided with the aperture 29. 30 represents lips or projections which are forced up from the body of end 28, in the same manner as lips or projections 23 are forced out of the body of end 18, of connecting member 16. The lips or projections are spaced to permit the head of a lag screw to come between them, requiring, as in the case of connecting member 16. The turning of said connecting member with the lag screw, when said lag screw is forced home prevents the removal of the lag screw when the construction is installed and the end 9 is in aperture 31.

When the construction illustrated in Figs. 1, 2 and 3 is to be installed in a window frame, a plurality of members 16 are first secured to the lower horizontal member X of the window frame a suitable distance apart. The bars 1, 3 and 4, are loosely connected together; and by laying the construction in a substantially horizontal plane, the apertures 15 in bars 3 are mounted on the vertical members 21 of connecting member 15. The connections 28 are secured in position in the side members X of the window frame. The lower sash is then raised sufficiently to permit the turning of bars 1, 3 and 4, into a substantially vertical plane. The upper sash is then lowered until the lower horizontal bar Y thereof is below the upper ends of vertical bars 4, and also below the upper ends of bars 1, and there secured by the bolt Z, (Fig. l). The bolt Z forms no part of this invention, but co-acts therewith to hold the window from being raised or lowered from the outside. The construction cannot be removed without turning it into a substantially horizontal plane, and the bar Y prevents such turning, from the outside of the window.

This window guard is thus firmly secured in place.

When a permanent window guard, such as is illustrated in Fig. 6, is to be secured to the window frame, a plurality of connecting members 33, 34, are substituted for the vertical bars 3 and 4, (Figs. 7 and 8).

Members 33, 3e, are provided with bends 35, so that the end 33 is in a plane parallel to the plane in which the end 34 is in. The end 33 is provided with the lateral aperture 36, and the end 34 is provided with the aperture 3'7. A screw or bolt, to form a pivot, may extend through the aperture 37 to secure the connecting member 33, 34, to a window frame, and a rivet may be extended through said aperture to connect said connecting member to the lower end of bars 1. 38, 39, Fig. 8, represents aconnecting member co-acting with the member 33, 34. The part 38 of member 38, 39, is extendible through, or engageable with slot 36, and is extended therethrough when the modification is installed.

40 represents an aperture in part 39 of member 38, 39, through which a rivet, 41-, extends.
